To all alf/2.0m it may concern:

Be it known that I, JOHN D. BOUGHNER, a citizen of the United States of America,

residing atV VYorba Linda, county of Orange,

`State of California, have invented a certain new and useful Drill-Rod Connection; and 1 Vdo hereby declare the following toA be a full,

olea r. and exact description of the invention, such as will enable' others'skilled in the art to which it appertains to inake and use the same. i

VThis invention relates to improvements in drill rod connection, more particularly to improvements fin the construction which is disclosed lin my Patent No. 1,075,896, dated October 14,1913.

' One object of the invention is to provide u novel and improved form of drill'rod connection which can be easily and quickly connected toV or disconnected from the drill rod.

Another object of the inventionl is to provide 'a novel andirnproved drill rod connection which is constructed and appliedto the drill rodV so as to overcome practical dilieulties heretofore due to crystallizationv and breakage of some partin-the drill rod connection.

Further objects of the inventionv are to provide a novel and improved construction for the drill rod connection which is comparatively simple in design; durable, convenient and effective in use; practical and commercial; and which facilitates manipulation and operation, and saves time and effects better working and results in'practice. With the above and other apparent objects in view, the invention may be said to consist in the provision of the novel and advantageous features and in the novel and improved construction, arrangement, and combination of parts as will be evident from the following description of the preferred embodiment of the invention, taken in connection with the accompanying drawings in which- Figure 1 is a broken view of the rod and drill to which the invention is applied; Fig. 2 is an enlarged broken view of the same; Fig. 3 is a longitudinal sectional view taken on the line 3 3 of Fig. 2; Fig. lis an enlarged cross-sectional view taken on the line #1 -fl of Fig. 3; Fig. 5 is a broken longitudinal sectional view taken on the line 5-5 of Fig. 4; Fig. 6 is a broken elevational view showing a modified form of connection of the cable to the crowfoot support; Fig. 7 is a plan view taken on the line 7-7 of Fig. 6;v

and Fig. 8is a broken sectional view showing sections of metallic sheathing on the cable.v -Y l The drill bit 10 may be of the usual or any vsuitable form, and it is preferably yprovided "with the passageways 11 and 12 for water to facilitate drillingv operations The ,hollow drill rod is preferably made up of sections 13 connected by the unions 14. Y' t Y I* Y The construction of the improved 4drill rod connection`which is applied tothe drillingl apparatus to permitfof easy'and quick recovery of the apparatus when it isbroken-v will now be described. Y f .f c

* A column of )four or fiveol' thesections 13 connected bythe unions 14 has thelthreade'd upper'and lower ends thereof screwedinto `one end of the hollow fittings lfand 15 which latter have the other endfthereof preferably formed tapered andl provided with -theannular shoulder 16. *On theta'pered end I l of eachV ofy the fittings 15 and 15- are screwed 'one end of the cylinders 17- and `17 l .f The Afit- 'tings 15 andi15Y and the cylinders 17 fand: 17

are thicker and therefore strongerthanVv the "sections l13 so that ifthe sections'13 are broken in use said fittings and cylinders will remain unbroken* The''fdrill bit 10 is l suitably connected to the cylinder 17 which is lowest in position.

A cable 18 has its upper end attached to the crowfoot 19 or other suitable support protected by sections 21 of metal sheathing so -that said cable is not likely to be cut or damaged when a break occurs in the hollow drill rod.

As shown in Figs. 3` and 5 the cable 18 at its lower and upper ends has its strands spread apart in the tapered bore of the boxes Vor sockets 22 and 22 and secured by babbitt or the like applied thereto. The head 20 and the crowfoot 19 are preferably provided with stems 23V and 23 which are screwed into the sockets 22 and 22.

As shown in Figs. 6 and 7 the crowfoot 24 may be split and provided with suitable clamping plates 25 which canbe connected together by the bolts 26 to clamp the cable 18 therebetween.`

willlllgpez disposedwiiiI lthe cylinder i7.

Froin the foregoing the construction and advantages of the improved drillrod connection will be understood by those skilled apparatus, the same construction can be duplicated according to the number' of Ajoined sectionsl of the .drill rodA as may be reqiiiredbythe .dept-h of the drilled hole 27 in the ground 28. `When a coluinn of the joined sectionsl?) is to be added to the construction shown inthedrawings, it lwill be understood thatuthe lower end of saicl col uniiiis screwed into a itting 1 5 onthe upper ,endiofl the cylinder 17, andthe head 2Q on the lower end of then'ext sectionof cable 18 Y I lll/'hen akbreal: occursin anvot the sections 13 of the drill rodand the latter is raised by suit.- vable ,1neans the vheads 2OV will engage the shoulders of the ittings l5 andthe sections lof tll, drilling apparatus are so tied together -that they can all be raised at the saine ,time

yI claim;

,l. Theiconibination 4with a hollow drill rod, o hollow fittings connected to the upperand lower end s of said hollowdrill rod and formed with shoulders, cylinders connected to said fittings, said cylinders bei 1'ig! tl iiclrer and therefore stronger than said hollow :drill red, a support resting on the shoulder of the upper tting, and a cable of tl'ilisfpateii't obtained for connected to said support and provided with a head disposed in the lower' cylinder, said head being norinally spaced from the lower itting and adapt-ed to engage the shoulder of said lower fitting substantially as and for the'laurpose set forth. Y

I2. 'l `he. combinati on with a substantially vertical hollow drill rod, of a fitting having one end thereof connected to the upper end of said hollow drill rod, and a fitting having one yend ,thereof connected to Vthe loweriendl of said hollow drill rod said f1ttingslb'eing hollow and each having the other einlthereot, orinedltape-red and provided withY 1ashoulder, ycylinders connected to said litt-ings, said cylinders being thicker and therefore strongei' tlia n. said hollow drill rod, a crowfoot support resting on the shoulder of the iirst nientioned litt-ing, a cahlezhaving its upper end attached to said support, andjfa head attached to the lower end Asaid cable and disposed in the lower cylinder, .head being nornially spaced from the second inentioned fitting and adapted to engage the shoulder of the second nientioned ttingsubstantially as and for the imposent forth. l f Intestiniony whereof; have signediny nanieto this speciication at Yorba Linda,
